ELECTRIC MASSAGE ANDVlBRATOiR MACHINE.

Specification of Letters Patent.

Patented May 22, 1906.

Application filed May 18, 1905. Serial No. 260,980.

To all whom it may concern.-

Be it known that I, SAMPSON W. MOON, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Electric Massage and Vi: brator Machines; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in electric massage and vibrator machines.

The object of the inventionis to provide a machine of this character which is adapted for use in massa ing the face, head, and body and for use by p ysicians in vibratory treatment and which may also be used in its larger or heavier forms for rubbing down and polishing all kinds of woodwork, furniture, &c., that are given a rubbed or polished finish.

Another object is to provide a massage and vibrator machine operated by electromagnets, the armature of which forms the vibrator-arm, said armature being pivotally mounted and evenly balanced by springs.

Another object is to provide means for regulating the speed and length of the vibrations, means being also provided for preventing the armature from striking the poles of the magnet, thereby making the machine practically noiseless.

With thcse and other objects in view the invention consists of certain novel features of construction, combination, and arrangement of parts, as will be hereinafter described and claimed.

In the accompanying drawings, Figure 1 is a perspective view of-the device, showing the same attached to the socket of an electric-light-circuit wire. Fig. 2 is a to plan view of the device with the u, )per iialf of the casing removed, showing the construc: tion and arrangement of the vibrator mechanism. Fig: 3 is a detail horizontal sectional view through the adj usting-scrcws for regulating the speed and length of the vibrations of the-armature. Fig. 4 is a detail sectional view through the outer end of the armature or vibrator-arm and the massage-tool, and Fig. 5 is a similar view through the cushion device for preventing the armature fron striking the poles of the magnet.

Referring more particularly to the drawings, 1 denotes the machine, which is here shown as consisting of a substantially ovalshaped casin 2, formed in two parts, the upper part of w 'eh is removably secured to t e ower in any suitable manner. To the lower part of the casing is secured ahollow handle 3.

Within the casing 2 is secured a supporting plate or frame 4, on which is mounted an electromagnet 5. Pivotally mounted on the frame or plate 4 is an armature 5, the outer end of which is bent at right angles to form a vibrator-arm 6. On the outer sideof the armature 5, near the pivoted inner end of the same, is secured a contact-spring 7, which is adapted to engage an adjustable contactpoint 8.

Adapted to bear against the outer end of the armature adjacent to the inner end of the vibrator-arm is an expansion or push spring 9, the opposite end of which is connected with an adjusting-screw 10, whereby the tension of the spring is regulated. Connected to the armature on the o posite side of'the magnet or near the pivota connection of the armature is a retractile spring 12, the opposite end of which is connected to an adjusting-screw 13, by which the tension of the spring is regulated. These springs are provided for the purpose of balancing the armature and also for the purpose of forcing the armature away from the magnet when the latter is demagnetized.

As the force of the armature when so separated would be thrown against the contactspring 7, the latter spring wouldsoon become useless unless the force of the armature when moved by the sprin 9 was checked. In order to check or relieve t e force of the armature, the retractile spring 12 is provided. These springs when properly adjusted will evenly balance the armature.

In order that the armature will be prevented from striking against the poles of the magnet, and thus creating a noise, a bumper or cushion is provided against which the armature vibrates. Said bumper preferably consists of a hollow or tubular screw 13, adapted to be screwed through a threaded aperture in a lug 14, formed on the plate or frame 4 The screw 13 is held in its adjusted position 1n said lug by means of a set-screw 15. In the hollow or tubular screw 13 is arranged an elastic cushion, which is preferably and is here shown as a rubber plug 14, but which may be a'coiled spring or any suitable form of cushioning device.

The contact-point 8 for the contact-spring 7 is formed on the inner end of an adjustingscrew 16', adapted to be screwed-through an apertured lug 17 secured to the frame or plate The outer end of the screw is provided with a knob 18, formed of non-conducting material, whereby the screw is adjusted in the lug 17 to bring the contact-point 8 into more or less close engagementwith the contact-sprin 7, thereby varying the speed and length of t e vibrations of the armature or evibr'ator-arm. be held in its adjusted positions without the use of jam-nuts, a coiled spring 19is arranged thereon between the inner end of the knob 18 and the lug 17, the tension of the spring holding the screw against casual movement.

On the knob 18 is secured a pointer 20, which when the knob and screw 16 are turned will move over a scale marked on the casing 2 and arranged to indicate the s eed of the armature and ,the'position of tie contactpoint 8 against the s ring 7.

Connected with t e ma net and the contact spring and point in t e roper manner are the terminals of the con uctor-wires 21 of the circuit, the opposite ends of which are here shown as connected to a condenser 22 of any suitable form and here shown as inclosed in .an ornamental casing. The condenser is here shown connected by short conductingwires 23 withv a plug 24, adapted to be engaged with the socket of an electric-light-circult wire. The conductor-wires 21 and 23 are insulated and inclosed in a suitable covering to form a flexible cord. By arranging conducting-wires or cord to be suspended thereby e se to the point of attac 'ng said conductor to the socket of the circuit-wires the condenser will be sup orted in an out-of-the-"way position.

On t e end of the vibrating arm maybe secured an suitable form of massaging-tool 25, said too being here shown as cup or bell shaped and formed of rubber.

A massage-machine constructed as herein shown and described willbe found to be simple, strong, durable, and comparatively inexpensive in construction, efiicient in operation, light in weight, and convenient and easily handled.

From the foregoing description,

taken in connection with the accompanying drawings, the construction and operation of'the invention will be readily understood without re uiring a more extended explanation.

arious changes in the form, roportion, and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.
